The present invention relates toapparatus for forming apattern of non -flaccid strands and more partlcularly to this general type various of Fig. illustrating forming mechanis of apparatus designed for, the produotionof ,ajpattern consisting of a series of longitudinal warp strand stakes.

s interlocked by spaced One object of the present invention is to provide apparatus for rapidly and efficiently producing a pattern consisting of longitudi nal strands interlocked by transverse stakes which are inserted in a plurality of planes in a manner to materiallyincrease the depth or i 7 thickness of the pattern and materially improve the appearance of the fabric.

The shafts are drven intermittently and in timed relation to the cross feed by a ratchet wheel 44 mounted on the shaft 36 and engaged intermittently by a pawl. 46 pivoted at 48 upon a rocker arm 50 loosely journaled on the shaft 36. as indicated clearlvin Figs. 1 and 2. The rocker arm is oscillated at theproper time intervals through a rotating cam 52 mounted upon a counter shaft 54 and connected to the arm through a lever 56 and an adjustable link 58. As shown more particularly in Fig. 2, the lever 56 oscillates about a fixed pivot 60 and is provided with a can; roll 62 atthe end opposite the link connection 58. The cam .roll is maintained in contact with the periphery of the cam 52 through a 831111 '64 connecting the hub of the lever with a fixed portion of the frame. Yieldengagement of the; pawl with the teeth ofthe ratchet is provided by the spring 66 interposedbetween a projection on the arm 5OI-an'da tail 68 formed on the pawl above the. pivot. The counter shaft 54 is journaled in the 'sioe bars of the frame above the main shaft 24 and is continuously rotated from the main shaft through a large gear 70, which meshes with the drive pinion 28. With this constructiony it will be evident that the shed forming members are revolved intermittently and luumson during t-he continuousrotationof the cam 52.

The longitudinal strands are conveniently guided to the revolving shed formers through the provision of a stationary guide bar 72 mounted on a cross beam 74 and havmg a 'series of gulde passages 76 formed therein, which receive the longitudinal 5 It isdesirable that the longitudinal strandsbe spaced in contact with one another and-in order to secure this relatively close spacing successive strand passages in the guide memberare'disposed above and below one another, as indicated in Figs. 1 and 5 The rotation of the shed formers draws the longitudinal strands through the stationary'guide member and disposes these strands on the opposite sides of a transverse shed passage. Thereafter the rotation of the shedforming members is stopped for a sufficient time interval to permit the'insertion of a cross stake in the passage thus formed. The cross stake is inserted through particularly in an opening 80 formed in the frame opposite one end of the shed forming members and having cooperating feed rolls 82 and 84 positioned opposite the entrance thereof. The upper feed roll 82 is provided with a grooved periphery approximating the diameter of the cross stake and is continuously rotated from a pulley 86 mounted upon the opposite end of a short shaft 88. Thispuh ley is driven by a flexible belt 90 passing through. the side bar of the frame and thence diagonally to a drive pulley 92. During its passage between thedrive pulley 92 and the smaller pulley 86, the belt. is caused to pass over 96 as indicated in Fig. 3. Mounted upon the shaft with the guide pulley 92 is a smaller pulley 98 which is driven from a pulley 100 through a flexiblebelt 102. The main drive pulley .100 is mounted upon the shaft24 and is rotated therewith; it will be evident that with this construction the stake feeding member 82 is rotated at a relatively high rate of speed. Cooperating with the groovedfeed roll 82 is an underfeed 84 which is adapted to enter the groove in the upper roll and engage the strandthere in. The lower feed member is loosely journaled upon the end of'a lever 104 pivoted upon the frame at 106 and adapted to he oscillated at predetermined intervals by a path cam 108. The path cam is connected to the lever 104 through a rocker arm 110 and a link connection 112. As indicated, the rocker arm is. normally maintained in contact with the periphery of the cam by a tension spring 114. The underfeed roll 84 is caused to maintain ayielding engagement with the strand by virtue of a inata slot connection 116 between the end of the lever 104'and the link 112 and a light spring 118' connecting the lever with the link. With this construction, when therocker arm 110 reaches a predetermined point on the periphery ofthe cam 108 the underf'eed' roll is elevated into the grooved. periphery of ment, the stake is automatically severed in-' side of the frame.

This severing of the stake is accomplished by an oscillating knife blade 120pivoted on the inside of the frame at 121 and'operated at'predetermined intervals by a rotary cam 122 connected to the knife blade through a rocker arm 124 and link-126. As indlcated', the knife blade is lUU I provided with a Cutting "edge 128 which shears the strand against the edges of an 'openingtorme'd in a'cutting plate 130, all

' as indicatedinFig; 8. Both the feed cam and cutting cam are mountedupon the counter shaft 54. The rocker arms 110 a'ndp124 are. loosely. journaled upon a counter shaft 60, which also carries'a rocker member 56 at its opposite end. I l T The; revolving shed; forming inembers which are shown in assembled relation-in Fig. 1 partially broken away to indicatethe strand'guide are illustrated more-particularlyin Figs. 5 to inclusive. Each of these shed formingmembers' comprises essentially a hub portion having a plural-' ity "of bars 144 disposed v about the circumwference." Interposed between the bars 144 is asecond series'"of b'ars'146 also disposed circumferentially of the hub. Each of these bars, as indicated more particularly in'Figs.

the other hand, the teeth formed on the bars 146 are disposed at a greater distance from the axis ot-rotation' thanthe adjacent teeth on the bars 144. Each bar is providedwith a longitudinal slot 150 and 154 respectively which forms the shed passage in conjunction with the cooperating shed forming member.

'As indicated clearly in Fig. 5, the two revolving shed forming members are so located with respect to one another thatthe h shed forming teeth upon the b'ar146 mesh with the teeth on the bar 144 mounted upon With this construction, shed passages are formed successively above and below a given plane, which in the present instance may be considered the plane of the straight longitudi- -nal strands. 'At the same time longitudinal ing 'therethrough' so that the cooperating high and low teeth deflect the longitudinal strands into positions where they project only slightly, if at all,'into the transverse 1 tom of one set of teeth and the tops of the 00- operating teeth is suflicient to permit inserw tion of a longitudinal strand without injury but engages the strand sufficiently to.
